"above the frame B (Figs. 1,- 4 and 5).

Pivoted on bolts 17 passing through bearings on the outer side of the vertical portion of each leg of the A frame, are side supports or outriggers 10, the bolts 17 also passing through the projecting flanges of dates secured to the outriggers (Fig. 6.) T e outriggers'l O are preferably triangular in form with the bases forming the pivoted ends, and when in an extended position they are secured in place'by brace beams 12, removably secured o a plate 15 securedtoand bent around the outer end of each outrigger and to a horizontal flange 35 secured to the car body (Fig. 4). On the under side of each outrigger 10 are secured sets of flanges 18 (Fig. 6) to provide for the supporting of the outrigger at any desired distance from the side of the car; preferably by a bolt 19 passed through a set of flanges l8 and the head of a screw jack placed on asuitable support S. Additional guys 13 may be secured to the top of the A frame and to ground anchors to preserve the stability of the frame under excessive lateral strain.

'lhederrick boom D, formed in two sections preferably of channel beams with lattice bracing, is pivotally securedby a bolt 7 (Fig. (5) running horizontally through flange members secured tozthe foot of the boom and the top of a swivel pivot member 36 which is seated in the car body between the le s of the A frame. The boom is raised and lowcred by means of tackle 9 leading from the to of the Aframe to the end of the boom (Big. 2); the boom is adapted to. be swung to either side by tackle of the boom to the 14 running fromthe end outer ends of the outriggers 10 (Fig. 3). At a point 8 (Fig. 1) adjacent its center the boom is hinged b means of a bolt 26 passing through vertical ilangcs on the lower sides of the adjoining ends of the boom sections. The boom is thus adapted to fold downward at the hinge in order that the strain of the rigging 9 may constantly act a ainst any tendency of the boom to fold up when extcndcd; in Fig. 7 is shown the upper sides of the adjoining end of the boom sections, wherein there is provided a plate 24 secured to and projecting beyond the end of one of the boom sections and adapted to estend over and be secured to the end of the other section by bolts passing through bolt holes 25; by this means perfect rigidity of the boom when extended is secured.

plate 24 (Fig.

Should it,

be desired or necessary to use a short boom, I have provided the lower or foot section of the boom, adjacent the upper end thereof, with a rigging pulley 40 and have prov ded 2) with a vertical aperturcd flange 39. The upper section of the boom having been removed the boom tackle 9 is attached to flange 39, 'the load hoisting tackle is suspended from the flange through which bolt. .26 ordinarily )asses, and is run over pulley 40, and the side rigging 14 having been adjusted the lower section is ready for use as a boom.

[n Fig. 8 the derrick and attendant parts are represented in their collapsed or lowered positions. in order to collapse the derrick the boom D is lowered to rest on the car or some suitablesupport, the bolts connecting the upper edges of the boom sections at their point of joindcr are removed, the tacklc E) is 'unfastcncd from the end of the boom and sccurcd to flange 3.) (scealso Fig. I), a 1d by means of the tackle the boom is raised, permittin the upper section thereof to fold down on the lower section, until the folded boom is in an upright position in front of and rent to thc A-trame, The braces cxtcnding from the outriggcrs 10 to the sides of thc car are then removed, the outriggers are swung in to a position parallel with the car, and assume an upright position when the braces are re moved from the A-framc and the A-framc and folded boom are lowered until the former rests on I beam 2 and the latter on I beam 1. This adjafolding or colla sing of the derrick structuremay be ctlectet without removal or adplstment of the rigging other than the attac ring llange39 as above described.

of rigging 9 to The location of the I-beams 1 and 2, the height of the frame, and the lengths of the boom and outriggers are preferably such that when the various parts are in their lowered or collapsed position, the most elevated point of any of the parts will be below or on a line with the roof of the engine house.

Having thus described my invention, what -I claim is:

1. The combination with a car of a folding boom carried thereby, comprising a plurality of pivoted sections adapted to be folded together and to be lowered upon the body of the car when folded.

2. The combination with a car of a foldin boom and a pivoted derrick frame carried thereby, connections between the frame and the boom, and an outrigger member carried by the frame.

3. The combination with a car of a folding boom and a )lVOttd dcrrick frame carried thereby, said oom comprising a plurality of sections adapted to be loldcd togcthcr, and said frame and said boom when folded being adapted to be lowered upon the car body.

4. The combination with a car of a folding boom and a pivoted derrick frame carried lilt) thereby, and an outriggermeinber carried by I boom and a pivoted derrick frame carriedthereby, and a su orting frame mounted on the car body, sairFboom com risin a plurality of sections adapted to be? and said boom and said derrick frame being ada )ted to be lowered longitudinally of the car ody upon said supporting frame.

6; The combination with a car of a foldin boom and a pivoted derrick frame carrie thereby, an outrigger member carried by the derrick frame, and a supporting frame mounted on the car body, said boom comrising a plurality of sections adapted to be folded together, said boom and said derrick frame being adapted to be lowered longitudinally of the car body upon said supporting frame, and said outrigger member being adapted to be swung inward of the car body.

7. The combination with a car of afolding boom and a derrick frame carried thereby, an outrigger member carried by said frame, connections between the frame and the boom, connections between the boom and the outrig er member, removable means for securing 'j the frame in an upright position, and removj olde together, ,b

able means for securing the outri ger member in osition outward of the car ody.

8. T 1e combination with a car of a folding boom and a derrick frame carried thereby, an outrigger member carried by said frame, connections between the frame and the boom, connections between the boom and the outrigger member, removable means for securing the frame in an upright position, and removable means for securim the outriggermember in position outward of the ear body,'said 00m and said frame being adapted to be lowered upon the car body.

9. The combination with a car of a folding boom, and aderrick frame carried thereby, an outrigger member carried by said frame, connections between the frame and the boom, connections between the boom and the outrigger member, removable means for securing the frame in an upright position, and removable means for securing the outrigger member in position outward of the car body, said boom and said frame being adapted to be lowered upon the car body, and said outrigger member being adapted to be swung ininward of the car body.

I In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
